One of those assaulted was a 14-year-old girl who prosecutors said continues to struggle.

“Her mom describes the victim now as being depressed, does not allow anyone to touch her, that the victim wakes up screaming from nightmares,” prosecutor Jessica Ballenger said.

Last month, WISN 12 News revealed a breakdown at the Milwaukee Police Department.

On Oct. 14, 2014, the crime lab identified DNA from a September 2014 sexual assault as Brown's, but the detective handling the case did not act quickly enough. Four victims were assaulted while police waited eight weeks to make an arrest.
